Abstract

The invention discloses equipment for evaluating the sealing property of an automobile rear axle housing, and the equipment is applied to solve the problems in the prior art that the existing tools for evaluating the sealing property of automobile rear axle housings are low in work efficiency. The equipment comprises a tool support, a workbench, an elevating mechanism, a rotating mechanism, a sealing and clamping mechanism, a water tank and a control box. The equipment is characterized in that the workbench is provided with a frame structure, a force guide rod is arranged between a front cross beam and a rear cross beam of the workbench, axle housing limiting blocks are arranged on the rear cross beam in a way of left-right symmetry, rear cross beam reinforcing plates are arranged in the mounting positions of the axle housing limiting blocks, and the rear cross beam reinforcing plates are wrapped on the outer side wall of the rear cross beam. The equipment has the characteristics of reliable performance, strong practicability and convenience in operation, and can greatly increase the production efficiency and reduce the purchasing cost.

Description

technical field [0001] The invention relates to a testing device for the sealing performance of automobile components, which is especially suitable for testing the sealing performance of rear axle housings of automobiles, and belongs to the technical field of testing. Background technique [0002] The main function of the automobile rear axle assembly is to carry the body, transmit power, and convert the longitudinal rotation of the transmission shaft into the lateral rotation of the left and right half shafts. The rear axle assembly is an important part of the vehicle chassis, which has extremely high safety requirements, and the rear axle housing, which carries the differential, reducer, half shaft, etc., also has high requirements on its sealing performance. The gear oil in the axle housing is sufficient without leakage, and the inspection of the sealing performance of the rear axle housing is listed as an important inspection item in the chassis assembly process.
